根据1979年国际水稻研究讨论会商定,1980年早造我所首次参加国际水稻所组织的国际水稻早熟品种产量鉴定圃试验。参试品种共28个(其中国际水稻研究所8个,印度7个,孟加拉6个,台湾省2个,泰国1个,菲律宾1个,巴基斯坦1个,伊朗1个,加上本所的“桂胡2号”作对照种)。试验田为砂质粘壤土,pH值6.35。本田每亩施氮素20.2斤,五氧化二磷13.6斤,氧化钾15.6斤。试验结果,27个品种中(有1个品种不抽穗),“桂朝2号”名列前茅(3个重复的产量均为第一名),
According to the 1979 International Symposium on Rice Symposium, I made my first trial in early 1980 to participate in the International Early Maturing Variety Yield Experiment organized by International Rice Research Institute. A total of 28 varieties (including 8 International Rice Research Institutes, 7 in India, 6 in Bangladesh, 2 in Taiwan, 1 in Thailand, 1 in the Philippines, 1 in Pakistan and 1 in Iran, together with the “ Guihu 2 ”for the control species). The experimental field is sandy clay loam with a pH of 6.35. Honda 20.2 kg of nitrogen per acre, phosphorus pentoxide 13.6 kg, 15.6 kg of potassium oxide. The results showed that among the 27 cultivars (1 non-heading), “Guichao No.2” was the highest (all three replicates had the highest yield)
